39-19 Background Noise
#2

Hi,
Looks like you did a swell job restoring it. You may want to consider that the noise is coming from the AC mains. Things like cell phone and laptop chargers and computer P/S use what are called switching p/s (read no power transformer) and these thing generate a LOT of Garbage on to the mains. The worst of it is when the battery is low in the devise that is being charged up. This puts the most load on the p/s. Unplug all of this modern junk and I'll bet you will a big improvement.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!

Well...pull out every single load of the transformer. For every winding. Unsolder if needed. Then re-do your dim bulb....morzh — 07:02 PM
